❓ FAQ
No. FS19915 is the plus-size element for Cummins ISX15 and Detroit DD13 to DD16 engines, with a 148 mm outside diameter. FS19727 and the FS19624 series are a different body size, so check the old element against the diameters on this page.
The coalesced water collects in the bowl under the element and is drained out through the drain valve at service time. Drain the bowl before the water level reaches the element, otherwise it gets pulled back into the fuel.
Yes. Prime the element with clean diesel so the high-pressure pump is not left running dry on the first start, then check the bowl and the drain for leaks with the engine running.
The supplier quotes 10,000 to 15,000 miles between changes. Shorten that if the truck runs dirty fuel or works in dust, and drain the bowl more often than you change the element.
The pack holds one separator element. The O-ring that seals the element to the housing is not in the box, so inspect the one on the housing and renew it if it is hardened or cut.
